Verdictwhich should you buy?
A7S II — Low-Light Video, Documentary & Available-Light Filmmaking: A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
RX100 VI — Travel & Vlogging: The RX100 VI trades fast apertures for a remarkable 24-200mm zoom range — giving it more versatility than any previous model. 4K/30p, 24fps burst, a pop-up EVF, and an articulating screen round out an exceptional compact package. Variable aperture limits low-light performance at the long end, but for travel and events where reach matters, there is no practical alternative at this size.
